f Aiaplicatien filed Jul 5, 1923. Serial No. e49,545l I ,The present invention relates to glass the "cover 16 of the boot. Attached to the feeders adapted for delivering individual shaft la-are propeller blades 17 whichexmasses or charges of molten glass suitable tend downward in the glass, the lower edges for entering the molds of'a glass forming of said blades being, spaced ashort distance machine. More particularly, the invention above the floor or the boot. The regulator 55 relates to that type of feeder in which the 1s rota-ted Continuously by means of aworm inolten glass is delivered through an outlet 18 running in mesh with'a worrn gear 19 opening or openings in the bottom of a keyed tothe shaft 14:. The wor1n18 iscarcontainer to which the glass is supplied, lied on a shaft 20 connectedthrough gears varying and controlling thedischarge. The shaft 14 is positioned'eccentrically An object of the invention is to provide 0f the outlet opening 13 so that the' blades improved means for controlling the dis 17 as they rotate are moved alternately over charge of glass, which will at the same time the outlet; Each blade as it approaches produce a. circulation of 'the glass within said outlet exerts an expelling force on the ,65 the container, adapted to prevent stagnation glass flowing "through the outlet; thereby and chilling of the glass atone side of the z ecelerating the flow; As the bladepasses outlet, thus preventing cold streaks orunbeyond the outlet, it exerts a retarding force evenness. in the telnpera-ture of the issuing I' upward pull On the glass. in S il lfl 20 glass.

As a result, two issuing gobs 26 are simultaneously produced. Two pairs of shears 2a may be provided, as shownin Figure 6, to simultaneously sever the suspended gobs 26.

It will be understood that the number of outlets might be increased, if desired. It will also be understood that the invention is not limited to the particular number of propeller blades 17 herein shown. The number can be increased. Also, in some instances a single propeller blade might be used either in connection with a single outlet or with a plurality of outlets.

Various other modifications may be, resorted to within the spirit and scope of my invention.

l/Vhat I claim is:

I 1. "Glass feeding apparatus comprising in combination a container for molten glass having a discharge outlet, a rotatable regulator extending into the glass at one side of the outlet with its axis parallel with the axis of said outlet, and means to rotate the regulator and periodically move portions over the outlet to effect periodic control of the issue of glass through the outlet.

2. Glass feeding apparatus comprising in combination a receptacle to contain molten glass, said receptacle having an outlet in the bottom thereof, a movable regulator in the glass in the receptacle, and automatic'means to move portions of the regulator in a horizontal circular path and periodically over the outlet to effect periodic control of the issue of glass through the outlet.

3. Glass feeding apparatus comprising in combination a receptacle to contain molten glass, said receptacle having an outlet opening in the bottom thereof, a movable regulator in the glass in the receptacle, and means to rotate said regulator about a vertical axis located at one side of the outlet and cause portions of said regulator to periodically sweep over the outlet to effect periodic control' of the discharge of glass through the outlet.

4. Glass feeding apparatus comprising in combination, a receptacle to contain molten glass, said receptacle having an outlet opening in the bottom thereof, a regulator comprising a rotatable propeller in the glass in the receptacle, and means to move the regulator in a horizontal circular path and periodically cause portions of the propeller to pass over the outlet and control the discharge of glass through the outlet.

5. Glass feeding apparatus comprising, in combination, a receptacle to contain molten glass, said receptacle having an outlet opening in-the bottom thereof, and a regulator within the receptacle comprising propeller blades, means to actuate the regulator and cause the propeller blades to work in the glass in the receptacle and control the disthe outlet by said regulator.

charge of. glass through said outlet, the propeller blades being successively moved over said outlet.

6. In a glass feeder, the combination of a furnace, a furnace boot or extension having an outlet opening in the floor thereof, means to control the discharge of glass through said opening comprising a vertical shaft extending into said boot at one side of the outlet, a propeller blade carried by and projecting laterally from said shaft, and means to rotate the shaft and cause said blade to periodically sweep over said outlet.

8. Glass feeding apparatus comprising, in combination, a receptacle to contain molten glass having an outlet opening in its bottom, means for circulating the glass within the receptacle comprising a device projecting into the glass and rotatable horizontally about an axis at one side of the outlet opening, means for rotating the device, and causing portions thereof to periodically sweep over the outlet "to successively expel and retard flow of glass through the outlet.

9. Glass feeding apparatus comprising, in combination, a receptacle to contain molten glass having an outlet opening in its bottom, means for circulating the glass within the receptac'le comprising a device projecting into the glass and rotatable horizontally about an axis at oneside of the outlet opening, and means to rotate the device and periodically move portions over said outlet opening to control the issue of glass through said opening, said outlet opening being beneath the path of rotation of said device.

10. In glass feeding apparatus, the combination of a container for molten glasshaving an outlet opening in the bottom thereof, a regulator withinthe glass in the container, and means to move'said regulator continuously in a definite horizontal path above said outlet opening and bring the regulator periodically over the outlet opening and thereby effect a periodic control of glass flow through 11. In glass feeding apparatus, the combination of a container for molten glass having an outlet opening in the bottom thereof, a regulator within the glass in the container, and means for moving said regulator continuously in a definite horizontal path above said outlet opening and bringing the regulator periodically over the outlet and thereby causing it to exert periodic expelling and retarding forces on the issuing glass.

12. In a glass feeder, the combination of a receptacle to contain molten glass having 1 an outlet opening in its bottom, a circulating device extending into the glass at one side of the outlet opening, and means for moving the circulating device ina circular path about a fixed axis spaced from that of the outlet and thereby periodically moving portions of 10 the circulating device over the outlet opening to cause periodic successive expulsion and retardation of flow of glass through'the outlet opening.
